Upgrading and migrating#
Learn how to upgrade HCL™ Launch elements, including the server, agents, and blueprint design server, and how to migrate data.
- Upgrading the server
You can upgrade the HCL Launch server to incorporate to a later version. Always upgrade agents, agent relays, and the blueprint design server in addition to upgrading the server. Upgrading the server, agents, agent relays, and blueprint design server are each completed independently. Unless specified, upgrade the server before you upgrade the agents.
- Upgrading high-availability installations
All servers that are configured for the HA feature must be on the same version. Thus, all servers must be upgraded at the same time.
- Upgrading agents
In most cases, you upgrade agents from the server interface, but you can also upgrade the agents from the command line. Always upgrade agents and agent relays in addition to upgrading the server.
- Upgrading agent relays
In most cases, you upgrade agents relays from the command line, but starting from 18.104.22.168 version, you can upgrade the server from the interface. Always upgrade agents and agent relays in addition to upgrading the server.
- Upgrading encryption key strength
When you upgrade the server from version 22.214.171.124 or earlier to a version later than version 126.96.36.199, you can upgrade the SSL encryption.
- Migrating the server database
The server installation files include a script that migrates the server database from Derby to another database system. You can not migrate from any database other than Derby.
